PARACHUTE FOR AEROPLANES Filed Aug. 3, 1931 25 427 4 M I W [gwuenkw4646/4/16 Patented May 1 6, 1933 UNITED STATES MILTON J. NOUSLAKIS, OFIBINGHLAM CANYON, UTAH PARAC'HUTE FOR AEROPLANES Application filedAugust 3, 1931. Serial 110.554,?26.

My invention relates to aeroplanes and has for its object to provide anew and eflicient parachute for lowering the plane to the earth when themotor has stalled or other accidents have happened to'make it anecessity to land without power and without gliding.

A further object is to provide a parachute for aeroplanes which iscarried medially of the wings or in the fuselage, and which parachutewill be opened by the pilot upon necessity, and which parachute whenreleased will be mechanically and instantaneously thrown up and out fromthe container.

A still further object is to provide a parachute which when releasedwill open at once and one which will be positive in its operation, dueto the fact, that the chute is thrown up and out from the container withsufiicient velocity to practically open the chute at once.

These objects Iaccomplish with the device illustrated in theaccompanying drawing in which similar numerals and letters of referenceindicate like parts throughout the several views and as described in thespecification' forming a part of this application and pointed out in theappended claims.

In the drawings in which I have shown the best and most preferred mannerof building my invention Figure 1 is a side elevation of a plane with mydevice mounted thereon.

Figure 2 is a plan view of a plane with my device thereon, part of onewing removed.

Figure 3 is a section of the cover and a side elevation of the pivotjoint and springs for the opening bar.

Figure 4 is a section of the free end of the bar with the parachute.attachment rod therein.

Figure 5 is a plan view of the box with the chute folded therein theopening bars and rods in place and the lid open.

Figure 6 is a plan view of the pivot joint and the elevating bar controlsprings enlarged to show the construction with the cover sectioned.

In the drawing I have shown the wings of the plane as A, the fuselage asB, and medially between the wing tips I provide a parachute containingbox C. The box C may be formed either in the wings orin the fuselage,depending upon the type of plane to which the device is attached.

The box C is provided with a spring controlled lid 1, which lid ispivotally or hinged- 1y secured to the back edge of the box by the hin e2 and is normally held closed by the control rod and hook 3. The spring4 holds the lid open when the hook is released. Notches 5 are cut in thefront and the two sides of the box to receive the free ends of theelevating bars 6, 7, and 8. The parachute D V is provided with threeattachment rods 9, 10 and 11, adapted to be inserted into the hollowendsof the bars 6, 7 and 8 respectively. The rodsare placed in the endsof the elevating bars and are easily and slidably removable therefrom,being only to open and elevate the perimeter of the chute. The rods aresecured to the perimeter of the parachute by any suit able means such assewing a ring 12-on the end of the rods to the perimeter of theparachute. The elevating bars 6 and 7 are attached to the plane Wings Aby forming the ends 13 of the rods into a hinge joint 14 and securingthejoint 14 to a hinge plate 15 by a pin 16. The bar 8 is attached in frontof the plane the necessary distance byan extension support bracket 17secured to the plane by one end and supported by the bracket 18. The end19 of the bracket 17 is turned up to fornrthe spring holding member andthe end of the bar 8 is made'similar to the ends of the bars 6 and 7,being a hinge joint 20 attached to the bracket 17 by a hinge joint 21and a hinge pin 22. i I

The ends of the plates 15 are bent up to provide spring engaging andhinge ends 23.

Eachbar is provided with'a yoke 24:, which yoke carries spring holdingarms 25, and springs 26 and 27 are attached to the arms 25 and to theends 28 of the plates 15 and to the end 19 of the bracket 17. Thesprings will be made sufficiently strong to raise the rods and bars fromthe box to a vertical position at the same time raising the parachutewith the rods.

The dotted lines in Figure 3 show the bars raised to vertical by thesprings 26 and 27..

A cover F is provided to cover the springs and hinges to preventfreezing or clogging by ice or snow and said cover is hinged to the endof the plate 15 and to the bracket 19 by the pin in the hinge 32.

Wires 31 brace the bracket 19 to the wings of the plane.

The operation of my device is as follows:

To open the parachute the aviator releases the catch hook 3 and thepower of the springs 26 and 27, and the spring 4; will throw the lid 1open at the same time raising the rods 6, 7 and 8 and their rods 9, 10and 11. These rods are controlled by springs and will be raisedinstantaneously, at the same time raising the parachute from thecontainer box and throwing it upward into the air currents, which aircurrents will completely open the parachute. The rod 8 being in front ofthe plane throws the parachute in such a position that the air currentswill naturally fill the parachute as the plane is traveling down throughthe air.

Having thus described my invention I desire to secure by Letters Patentand claim:

1. In a device of the class described the combination of a box mountedon the top of an aeroplane; elevating bars hingedly connected one, toeach plane wing and one, to an extension in front of the plane; springsto actuate said bars and raise them when their free ends have beenreleased; a parachute secured to the plane by the usual cords and having attachment rods secured to the perimeter thereof, said rods to fitinto the ends of the elevating bars and to slide therefrom when theparachute is opened; and means to release the lid of the box to allowsaid bars to raise therefrom.

2. In a device of the class described the combination of a box mountedin the top of an aeroplane; a parachute carried in said box having theusual cords connecting the parachute to the the aeroplane; attachmentrods secured to the perimeter of said parachute; elevating rods securedpivotally to the wings, and one elevating rod secured pivotally in frontof the plane; springs carried on each rod to raise the rods to avertical position, one end of the springs being secured to the plane andthe ends of the rods being hollow to receive the attachment rods of theparachute; and means to open said box to release said elevating rods andthe parachute from the box.

In testimony whereof I have aflixed my signature.

MILTON J. NOUSLAKIS.
